Abstract:

During the infection process, the enveloped virus hijacked the glycosylation system of the host cell to modify its own antigen, and escape from the immune monitoring of the host. Moreover, the glycosylation modification to the envelope protein, which played the antigen shielding effect, made the development of vaccine more difficult. On the other hand, the structure of the modified polysaccharide against the major epitope also had a spatial reconstruction effect. Therefore, the construction of neutralizing antibodies to the enveloped virus was related to the structure of the modified glycan. In addition, the glycosylation modification of antigen proteins was also associated with virus recognition, adhesion, tissue tropism, quality control of viral particle assembly, toxicity and infectivity. The current advances in this field were reviewed in this article.

Key words: Virus, Antigen, Glycosylation, Glycoform, Glycan-shielding
